Dagdara was born in Andor in the year 848 NE and went to the Tower in 863 NE. After spending seven years as a Novice and five as Accepted, she was raised to the shawl in 875 NE.

It was said that Dagdara knew more of Healing than any two other Yellow sisters, till the arrive of Nynaeve and her new Healing weaves. She was among the best healers in the traditional Aes Sedai method, almost on the same range of Samitsu and Suana.

She was present in the Little Tower when Nynaeve Healed both Siuan Sanche and Leane Sharif of stilling, completely shocking everyone. Dagdara immediately asked, in a strangled voice, what made Nyneave think of using Earth and Fire. She then criticized her technique and said that she "used Fire and Earth as if she were trying to bore a hole through stone".

A list from Verin Mathwin confirmed that Dagdara was of the Black Ajah, but we don't know if she was one of the fifty Black sisters to be executed in the rebel camp or one of the twenty able to run away.
